Voice-Controlled Noise Pollution Logger Kit with ESP32-S3 WakeNet

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Build a device that listens to the world around you—literally. This kit lets you create a noise pollution monitor that logs sound levels and responds to your custom voice command by toggling a lamp or appliance. Powered by an ESP32-S3 running WakeNet, it works completely offline, so your voice data never leaves the board.

What You'll Build

You'll build a standalone environmental logger that measures and records noise levels in decibels on the serial monitor. Say your training keyword—like "compoden on"—and it instantly triggers the relay to switch a connected lamp or fan. No internet, no cloud, just on-device keyword spotting. It’s a complete, real-world IoT monitoring system that anyone with basic electronics can assemble in an afternoon.

What You'll Learn

• Configuring the INMP441 I2S microphone for high-quality audio capture
• Training and deploying a WakeNet keyword spotter on the ESP32-S3
• Interfacing a relay module to switch AC or DC loads safely
• Logging sensor data and executing voice-triggered events in firmware
